I always thought you had to sand old paint off before repainting, but my neighbor's trick saved me a weekend.
I was getting ready to repaint my kitchen cabinets, which had this thick, glossy finish from the 90s. Everything I read said to sand it all down to bare wood for the new paint to stick. I bought a big orbital sander and a ton of 80-grit paper, dreading the dust and the time. Then my neighbor Mike, who flips houses, came over and saw me setting up. He said, 'Willow, you're killing yourself. Just use a liquid deglosser.' I was super skeptical, but I got a bottle of Zinsser's B-I-N deglosser for about $15. I wiped it on with a rag, waited ten minutes, and the surface was totally dull and ready for primer. It took maybe an hour for the whole set. One side says you must sand for a perfect bond, the other says a chemical deglosser is just as good if the old finish is sound. Has anyone else tried this method on cabinets, and did the paint hold up over time?
